Dear: thuy hàng

I hope this email find you well.

You asked me how I improved Mỹ English pronunciation,so I wanted to share some tips that worked for me

Firsltly,I made sure to listen to native speakers as much as possible, through movies,music,and podcast. This helped me get used to the nature rhythm and intonation of the language.

Second,I practiced speaking to myself in front of a mirror every day. It felt silly at first,but it built my confidence and helped me identify my problem areas

Finally,I used a language exchange app to chất with native speakers. They corrected my mistakes, which was incredibly helpful

I hope these tips help you too! Let me know how you get on.
